Busbar connector

Abstract

This invention discloses a bus connector, including an insulating body, conductive terminals, and a position identification component. The insulating body has a forward-through insertion groove, and the conductive terminals protrude inward into the insertion groove. The position identification component is fixed to the insulating body and includes multiple first conductors and one second conductor. Each first conductor includes an elastic arm with a first contact portion and a second contact portion. The second conductor has multiple openings. Each first contact portion passes through a corresponding opening and protrudes outward from the insulating body, while each second contact portion abuts against the inner surface of the second conductor. When the first contact portion is pushed inward, it causes the second contact portion to disconnect from the second conductor, thereby disconnecting the electrical connection between the first conductor and the second conductor. The first and second conductors of this invention are normally closed, with the first conductor located on the inner side. This facilitates the setting of the elastic arm length and reduces the risk of elastic arm failure.

[0007] Component symbol explanation: Power interconnect device 1000, bus connector 100, bus assembly 500, panel 600 Insulating body 10, insertion slot 11, first sidewall 121, second sidewall 122 Channel 141, fixing groove 142, protrusion 15 Conductive terminal 21, detection terminal 22, grounding component 23 Position recognition component 30A, first conductors 30, 31, 32 Elastic arm, first elastic arm 311 Elastic arm, second elastic arm 321 First contact parts 3111, 3211, second contact parts 3112, 3212 Cable 33 Second conductor 40, opening 41, elastic beam 42 Cable 43, fixing piece 441, guide piece 442 Busbar 51, Outer shell 52, side wall 521, position 53, opening 531. Detailed Implementation

[0008] The technical solution of the present invention will now be described with reference to the accompanying drawings in this embodiment.

[0009] Figures 1 to 6 A power interconnect device 1000 of the present invention is shown, comprising a plurality of electrical connectors and an elongated bus assembly 500. The electrical connectors are configured as bus connectors 100, with the plurality of bus connectors 100 mounted on a panel 600 and the bus assembly 500 mounted on a rack side. The bus connectors 100 are connected to corresponding power supply units (PSUs) to transmit power. The bus connectors 100 mate with the bus assembly 500, each bus connector 100 being adapted to connect a power supply unit to the bus assembly 500. The bus assembly 500 includes a bus 51 and a U-shaped housing 52, the bus 51 having a positive plate and a negative plate within the housing 52.

[0010] The housing 52 has multiple positions 53 on one side wall 521, each configured to accommodate a bus connector 100. In this embodiment, the side wall 521 of the housing has an opening 531 at each position 53. The multiple openings 531 at each position 53 can be configured in a unique arrangement, such that even when the bus connector 100 with the same structure mates with the bus 51 in different positions, the state modes of the first conductors 31 and 32 of the position identification component 30A may be different. Different arrangements and numbers of openings produce different position information identifications. The state of the first conductor depends on the state of the first contact portions 3111 and 3211 of the first conductor, such as being pressed down by the housing 52 or located in the opening 531. In this embodiment, there are 64 positioning assignment methods.

[0011] refer to Figures 7 to 18Each bus connector 100 includes an insulating body 10 and conductive terminals 21. The insulating body includes opposing first sidewalls 121 and second sidewalls 122, and a insertion groove 11 located between the first and second sidewalls and extending forward. The conductive terminals 21 protrude inward into the insertion groove 11. The insertion groove 11 is used to insert the bus 51. When the bus 51 is inserted, it contacts the conductive terminals 21 located on both sides of the insertion groove 11, thereby forming a power conduction path. A position identification component 30A is fixed to the outside of the first sidewall 121. A grounding component 23 is fixed to the outside of the second sidewall 122 for contacting the conductive housing of the power supply unit. A pair of detection terminals 22 are disposed on opposite sides of the insertion groove 11 and are used to detect whether the bus 51 is accurately inserted.

[0012] like Figures 10 to 18 As shown, the location identification component 30A includes a plurality of first conductors 30 and a second conductor 40, each conductor being connected to a cable 33, 43 extending out of the insulating body 10. The first conductors 30 are configured as identification conductors, and the second conductors 40 are configured as return conductors, located outside the first conductors 30. Each first conductor 30 includes a resilient arm 311 / 321, with a first contact portion 3111 / 3211 and a second contact portion 3112 / 3212. The second conductor 40 has a plurality of openings 41. Each first contact portion 3111 / 3211 protrudes outward from the insulating body 10 through a corresponding opening 41, and each second contact portion 3112 / 3212 abuts against the inner surface of the second conductor 40. When the first contact portion 3111 / 3211 is pushed inward, the second contact portion 3112 / 3212 is disconnected from the second conductor 40, thus disconnecting the electrical connection between the first conductor 30 and the second conductor 40. In this invention, the first and second conductors are normally closed, with the first conductor 30 located on the inner side. This facilitates the setting of the elastic arm length and reduces the risk of elastic arm failure.

[0013] In this embodiment, six first conductors 31 and 32 are provided. The first conductors are divided into two rows. The first conductors 31 in the first row have a first elastic arm 311 extending rearward, and the first conductors 32 in the second row have a second elastic arm 321 extending forward. The first elastic arm 311 is located in front of the second elastic arm 321 and aligned with the corresponding second elastic arm 321. Each elastic arm has a first contact portion 3111 / 3211 and a second contact portion 3112 / 3212. The second conductor 40 has multiple openings 41 corresponding to the elastic arms. The first contact portions 3111 / 3211 protrude outward through the corresponding openings 41 and extend outward beyond the outer side of the first sidewall 121. Therefore, the first contact portions 3111 and 3211 protrude beyond the second conductor 40, while the second contact portions 3112 / 3212 are mechanically connected to the second conductor 40 to achieve a normally closed state. The first and second conductors are directly inserted into and fixed in the insulating body, reducing their space occupation.

[0014] In this embodiment, each elastic arm 311 / 321 extends obliquely, the first contact portion 3111 / 3211 is formed by bending inward in an arc shape from the elastic arm, and the second contact portion 3112 / 3212 is formed by bending from the end of the first contact portion into a horizontal structure.

[0015] like Figure 14 and Figure 17 As shown, the insulating body 10 defines three forward-extending channels 141, within which the first conductor 30 is accommodated. The three first conductors 31 of the first row are fixed to the bottom of their respective channels 141, and the three first conductors 32 of the second row are suspended and fixed to their respective channels 141, located outside the first conductors 31 of the first row. Thus, the first conductors 31 and 32 of the first and second rows are separated from each other. The first conductors 31 of the first row are inserted into the channels 141 from front to back, and the first conductors 32 of the second row are inserted into the channels 141 from back to front. The second conductor 40 is inserted into the insulating body 10 from front to back, located outside the first conductors 31 and 32. It can be seen that the interference portion of the first conductor 32 of the second row is fixed within the fixing groove 142 to fix and position the first conductor 32.

[0016] The second conductor 40 is a metal plate with six openings 41 arranged in two rows and three columns. Elastic beams 42 are stamped between adjacent columns, extending outwards in an arc and configured as grounding components. Multiple fixing tabs 441 are bent from the front edge of the second conductor 40 and fixed to the protrusions 15 of the insulating body 10. Multiple guide tabs 442 are inclined inwards into the channel 141 to avoid impact from the insulating body 10 and the busbar 51.

[0017] When bus connector 100 is inserted into bus assembly 500, refer to Figure 18As shown, this illustrates the operation of a position identification component in one of the bus connectors. The sidewall 521 (the side without an opening) of its housing 52 contacts the first contact 3211, pushing it away from the second conductor 40. This causes the second contact 3212 to move away from the second conductor 40, resulting in the first and second conductors being disconnected from each other. This generates a unique position information code. The position information code and status can be represented in any suitable manner; for example, a "0" signal can be used when the identification conductor is disconnected from the return conductor, and a "1" signal can be used when the position identification conductor remains in contact with the return conductor.

[0018] Those skilled in the art should recognize that the above embodiments are merely illustrative of the present invention and are not intended to limit the present invention. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of the present invention fall within the scope of the present invention.
